What problem does it solve? When an implementer hands work off for review in a Kanban workflow, someone must independently verify the deliverable against the original acceptance criteria instead of rubber-stamping the handoff summary. This Skill provides a structured review procedure that produces a single evidence-backed verdict. ## Core Features & Use Cases - Independent verification: Reads the task record with kanban_show, inspects the actual deliverable, and runs builds, tests, and lint checks before deciding. - Round-based review lenses: Rotates between artifact, execution, and contract lenses across review rounds so repeated reviews catch different defect classes. - Three terminal verdicts: Approves with kanban_complete, returns correctable defects with kanban_request_changes, or escalates human decisions with kanban_block. - Use Case: An implementer submits a review_requested handoff claiming a bug fix passes tests. The reviewer checks out the change, runs the test suite, maps each acceptance criterion to evidence, and either approves with a concrete summary or sends back specific, reproducible findings. ## Quick Start Ask the agent to review the current Kanban task in the review lane by reading the handoff with kanban_show, verifying the deliverable, and recording a verdict.
